精密机械加工折柳盘甩油盘叶轮锁母
，CNC加工的汗青已经经历了长达半个多世纪
，NC数控系统也由最早的仿照信号电路节造发展为极其复杂的集成加工系统
，编程方式也有手工发展成为智能化、壮大的CAD/CAM集成系统。

Precision machining of folding discs, oil slingers, impellers, and locking nuts has a history of over half a century in CNC machining. NC numerical control systems have evolved from the earliest analog signal circuit control to extremely complex integrated machining systems, and programming methods have also evolved from manual to intelligent and powerful CAD/CAM integrated systems
